ATI显卡在Debian squeeze中使用开源驱动并开启3D

sjustc

经过屡次的尝试，终于解决了ATI显卡在Debian squeeze中使用开源驱动，启用3D加速。
显卡型号：ATI  Mobility Radeon X2300
开源驱动：radeon
需要安装firmware-linux-nonfree（关键）
radeonhd驱动貌似不如radeon好，在启动gdm时还会白屏。
使用google-earth，可以识别已开启3D加速，但运行一会就会卡住，风扇狂转，所以3D虽然开启，但性能不行。

xorg.conf如下：

Section "Module"
  Load  "glx"
  Load  "dri"
  Load  "drm"
EndSection

Section "ServerLayout"
    Identifier    "Xorg Configured"

EndSection

Section "Extensions"
         Option  "Composite" "1"
EndSection

Section "ServerFlags"
         Option      "AIGLX"         "on"
EndSection

    EndSubSection
EndSection

Section "DRI"
    Group        "video"
    Mode         0666
EndSection

Section "ServerFlags"
    Option "DontZap" "yes"
EndSection


测试效果：

$ glxgears  
6213 frames in 5.0 seconds = 1242.592 FPS
6219 frames in 5.0 seconds = 1243.622 FPS
6416 frames in 5.0 seconds = 1283.006 FPS
6429 frames in 5.0 seconds = 1285.762 FPS


查看是否开启3D：

$ glxinfo
